Description

Quick-acting granulating machine

This utility model relates to a kind of pulverizer, particularly a kind of Fast granulate machine that is used for industries such as pharmacy, chemical industry, food.

Before the present utility model, the granulation process of industries such as pharmacy, chemical industry, food generally all adopts swing or squash type granulation machine, granular size after its manufacturing, the fragmentation is even inadequately, particle breathability, poorly soluble, and this machine labour intensity is big, big energy-consuming, length consuming time, exists the buildup dead angle can cause cross-contamination; Direct employing granulator is also arranged; the granulate not but granulator is only granulated; the granular size of making is very inhomogeneous, and this all can influence the production of later process and the quality of finished product, and the advanced tablet machine that particularly present pharmaceutical industry is adopted requires very high to particulate uniformity coefficient.

The purpose of this utility model just is in order to overcome this defective of prior art, and a kind of and the Fast granulate machine matching used brand new of granulator are provided.

Scheme of the present utility model is: Fast granulate machine comprises hopper, cylindrical shell, the intravital screen drum of tube, stator, rotor and motor and discharge nozzle; Hopper and cylindrical shell are connected by flange separately; One side of cylindrical shell is communicated with discharge nozzle; Rotor is positioned at the cylindrical shell bottom and is driven by motor output shaft; Screen drum is the opening cylinder that has big or small consistent sieve aperture on the perisporium equably, is fixed with one with rotor; Stator is made up of the some pulverizing bars that are uniformly distributed along the circumference and upper flange thereof and lower flange, is positioned at screen drum and leaves the gap.The uneven raw material of size enters screen drum from hopper, under action of centrifugal force, discharges from the sieve aperture of the certain rotation screen drum of specification, through the discharge nozzle discharging after pulverizing the bar collision with the stator that does not rotate.

Can be provided with some scraping articles radially in described rotor bottom, blow off the dust that is attached on the cylindrical shell so that when rotor rotation, produce wind-force.

Can have a pore from the side at the lower flange place of described cylindrical shell, when pelletizing machine is worked, blow into compressed air to blow off the minute quantity dust screen drum rotor and the cylindrical shell fit clearance, guarantee that better machine run is normal from this pore to the rotor lateral wall.

Can connect a cutting blade at the central boss top of described rotor, with the bigger or harder bulk raw of cutting viscosity.

Compared with prior art, this utility model volume is little, easy to operate, noise is low, granulate is even, and global design does not have the buildup dead angle, and is convenient to clean, and can stop material cross-contamination accident effectively, thereby greatly improve work efficiency and product quality.

Embodiment is described in further detail this utility model below in conjunction with accompanying drawing.

As shown in Figure 1, Fast granulate machine comprises hopper (1), cylindrical shell (2), tube intravital screen drum (3), stator (4), rotor (5) and motor (6) and discharge nozzle (7);

Cylindrical shell and internal structure such as Fig. 2, shown in Figure 3, cylindrical shell is made of upper flange (21), barrel and lower flange (22), and a side of barrel is communicated with discharge nozzle (7), and as shown in Figure 1, the hole that allows motor drive shaft penetrate and lay rotor shaft is left in the bottom; Rotor (5) is positioned at cylindrical shell (2) bottom, its central authorities are a boss and link to each other with motor drive shaft (61), its upper surface is fixed with a wing cutting blade (8) by screw (82) and pad (81), and this blade is mainly used in cutting and falls into the bigger or harder bulk raw of cylindrical shell bottom viscosity; Screen drum (3) is the opening cylinder that has sieve aperture (not shown) of the same size on the perisporium equably, and its top edge is equipped with flange (31), and lower limb then welds one with rotor (5) periphery; Stator (4) is made up of the some pulverizing bars (41) that are uniformly distributed along the circumference and upper flange (42) thereof and lower flange (43), and as shown in Figure 6, it is positioned at screen drum (3) and leaves the gap;

The structure of hopper (1) such as Fig. 4, shown in Figure 5, comprise hopper cover (11), hopper body (12), lower flange (13) and backgauge frame (14), hopper cover (11) is made up of two parts and is linked to each other with hinge (17), wherein right part and hopper body (12) are connected, left part links to each other with hopper body (12) by pilot pin (15), and is provided with handle (16); Backgauge frame (14) is the rigid support of a cross or net palisade, is used for preventing that too big feed block from entering following cylindrical shell (2); The lower flange of hopper (13) is connected with the upper flange (21) of cylindrical shell by bolt; If be used for auto feed, then also can leave charging aperture covering, and set up auto feed and take over (18);

During work, motor (6) drives related cutting blade of rotor (5) (8) and screen drum (3) rotation, the uneven raw material of granule adds from hopper (1), after constantly colliding through the cutting of cutting blade (8) with the pulverizing bar (41) that does not rotate, under action of centrifugal force, just granule of uniform size can be discharged from the sieve aperture of rotation screen drum (3) constantly, after discharge nozzle (7) discharging.

Described stator is pulverized the quantity of bar (41) and is not limit, decides on actual needs, and be the best generally with three.

Better, as Fig. 3, shown in Figure 7, mill out some radial grooves and settle some scraping articles (51) in rotor (5) bottom, be radially setting among Fig. 7, and preferably have at least a scraping article to stretch out rotor edge, scraping article (51) can produce wind-force and blow off the dust that is attached on the perisporium of cylindrical shell bottom when rotor (5) rotates like this.Figure 8 shows that the another kind of better scraping article of similar tangential setting, Figure 9 shows that the best volute setting that is.The quantity of described scraping article is not limit.Described scraping article also can be connected with other connected mode and rotor bottom.

Can also locate to open from the side a pore (23) to rotor (5) lateral wall at the lower flange (22) of described cylindrical shell; as shown in Figure 1; when pelletizing machine is worked; blow into compressed air to blow off the minute quantity dust rotor (5) and cylindrical shell (2) fit clearance, so that guarantee that better machine run is normal from this pore (23).

In addition, can also open several screws (52) at rotor (51) top, so that when changing the screen drum (3) of different size, can be connected with drawing tool, thus take out screen drum quickly and easily (3) and rotor (5).

The sieve aperture of described screen drum (3) perisporium can have different shapes and size as requested.
